Overview
Image and video media upload types, size limits, and other requirements for X/Twitter, Facebook, Instagram, LinkedIn, YouTube, Google Business Profile, Telegram, Pinterest, Telegram, TikTok, & Reddit.
Image and Video Posting Requirements
When posting to the /post endpoint, it is important to note the following requirements. Please only select either a video or image(s) since no social network support posting a video and images in the same post.
Accepted File Types
Files have an accepted file ending type (extension), such as jpg, jpeg, png, webp, gif, mp4, mov, or avi, with content-types such as image/jpeg or video/mp4.
If the media URL has special characters, e.g. ñ, please encode the special characters before sending.
Please see below for details on each network.
Maximum Images
Max images accepted per platform in a single post:
- Facebook Pages: 10 images, including a carousel post.

- Google Business Profile: 1 image.
- LinkedIn: 9 images.
- Pinterest: 1 image.

- X/Twitter: 4 images.
Maximum Videos
Only one video is allowed per post for X/Twitter, Facebook, LinkedIn, Instagram, Pinterest, TikTok, YouTube, and Telegram. Reddit does not yet support videos.
Please be sure your video URL ends in an accepted video extension such as .mp4 or .mov, depending upon the network.
For example,
- Accepted: https://mysite.com/video.mp4
- Not Accepted: https://mysite.com/video.mp4?code=30s93
We recommend for larger video files over 50 MB create a scheduled post with the scheduleDate parameter for async processing.
Be sure to also check the upload speed of your media URLs to prevent timeouts at the social networks. If the media file can not be downloaded within approximately 5 minutes a time out will likely occur.

Length: 60 seconds
